Creating new version of migrations


#1

I have a migration file like _create_posts.rb .

Now I want [anotherdatetime]_create_posts.rb with some changes different
from older migration that I can run with … rake db:migrate
VERSION=[anotherdatetime].

How can I create [anotherdatetime]_create_posts.rb, which is basically a
new version?

you probably don’t want to create the posts table again, you likely
want to change the existing schema. just make a new migration like
so:

"ruby script/generate migration ‘do_something_else_to_posts’ "

and then use the add_column, remove_column, rename_column, etc…
methods for migrations.
